Executed pre-completion checklist — third sibling of /prospect (before execution) and /retrospect (after shipping). Six checks, three outcomes each (PASS/FAIL/INVALID); an unrun check blocks the verdict. Catches failures that emit no error: a check whose FORM bounds what it finds, and a decision correct in isolation but wrong in context. Use BEFORE claiming done/fixed/shipped/verified/'none fou...
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# /preflight — the checklist you run before you report
`/prospect` looks forward at a plan. `/retrospect` looks back at shipped work. **This runs at the
moment in between: you believe you are done, and you are about to say so.**
## What this is NOT
**It is not `superpowers:verification-before-completion`,** which owns the principle — *no completion
claim without fresh verification evidence* — and owns it well. That skill answers **whether** to
verify. This one answers **what to verify**, and specifically: the checks whose *absence produces no
signal at all*.
If you have not internalised the Iron Law, read that skill first. This one assumes it and adds the
cases where you ran a verification, it passed, and the thing was still broken.
## The two failure families this exists for
Every check below descends from one of these. Neither produces an error, a failing test, or a warning.
1. **The check's FORM bounds what it can find.** A search whose pattern bounds its result; a review
whose scope bounds its result; a probe whose anchor bounds its result. The instrument reports
truthfully about the thing it measured — and you asked it the wrong question.

The line at the top of this page pins the label git:20260819.2e7ae9e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
A 17 of 17 checks passed. Fixed automatic checks with no AI involved, so the same checks give the same answer every run.
